The new CEO will not tolerate new unethical behaviour.
Hopefully he will also slowly eradicate the existing unethical behaviour.

(Cycling obviously, but the genetics behind VO2max apply across different types of physical activity.)
As you say, the first few test numbers correspond just to simple divisor checks:-
Prime 3 paired with check number 6 (binary 110). So 1 << (n % 3) will only ever be 'safe' if n % 3 == 0, which is 'super bad' as you put it.
(2^3)-2 = 6
(2^5)-2 = 30 so this is a similar division check
(2^7)-2 = 126 ditto
I think these are just here as distractions as it starts to sometimes do different things at p=11
11 is paired with check number 1026, which is (2^10)+2 not (2^11)-2). So under what conditions does:-
( 1 << (n % 11) ) & 1026 != 0
Given 1026 only has two bits set (1024 and 2) it's a rather specific test for (n%11) = 1 or 10. All other residues would be safe.
Don't have time to investigate further for the other primes and check numbers but I can only think of some kind of p-1 or p+1 smoothness they can detect this way.
He forces them to connect to his own AP and forwards all traffic to the destination so that the client is unaware it has been redirected.
He then forces the client to re-install the key which (on anything that is derived from wpa_supplicant e.g. Linux, Android, etc) the client has blanked out after first use, so the key it reinstalls is now all zero bytes.
He can continue to forward the traffic to the destination so that the client gets responses, but now he can decrypt all of the traffic too.
For clients that re-install the correct key (which the account does not recover in any way) the attacker has to rely on snooping enough encrypted data in order to perform a birthday attack as the key re-installation also resets the frame counters which leads to nonce-reuse which is a problem in ciphers like AES-GCM.
The client is tricked into moving to what it thinks is the same WiFI network running on a different channel, but is actually the attackers network instead.
> The attacker doesn't need to know the WPA2 password but it accepts the connection setting the encryption to zeros.
The attacked doesn't need to know the WPA2 password and (for Android and Linux clients) the client then defaults to an encryption key of all zero bytes.
> The client thinks it is connected to the original wifi network and continues as normal.
Yes.
> Wifi traffic is intercepted and unencrypted.
Wifi traffic is intercepted and can be decrypted (since the encryption key - all zero bytes - is now known).

More than likely a couple who are already earning ~£70k/year each probably already have some equity in a current home, so a £1m home might not be much of a step up for them.
I probably will too (currently on an iPhone 5) given that my current strategy is to replace my phone every 2 years by buying a refurbished model with 12 month warranty for ~£150 from eBay. I usually get ~£50 or so for each old phone so the physical phone only costs me £4 a month.
4GB data (4G), unlimited texts and unlimited minutes for ~£20 a month here in the UK. Was always amazed at the price of plans in the US, luckily I never had to pay my own bill when I lived there.
Yep, which is why I switched to decaf. Still the same taste (there are ok decaf coffees out there) but none of the bad effects of excessive caffeine.
(Most decaf still has ~10% of the caffeine of regular coffee, but even with 4 or 5 cups of decaf a day it's not enough for dependency; I get no withdrawal symptoms if I stop for any length of time).
I still drink the odd normal coffee (if someone/somewhere doesn't have decaf) but a maximum of one a day otherwise it will affect my sleep that night; it also gives me a proper coffee buzz for the short period after drinking it.
Sounds similar to what I used to drink. I now drink similar amounts of decaf black coffee a day and sleep a whole lot better. This is partly why I quit and definitely why I won't go back to regularly drinking normal coffee (it's been 6 years or so).
(Yes, I know decaf still contains ~10% of the caffeine of normal coffee, this just means I'm down to the equivalent of half a cup of coffee a day, which is below dependency levels as I get no withdrawal effects if I stop this for a few days.)
Once you've done that you should look at what other services you rely significantly upon and see about mitigating the risk there by having an alternative ready to go (or even sharing the load).
At a previous startup we realised we relied wholly upon Mandrill and so reimplemented the sending code so that half of the emails went out via Mandrill and the other half by SendGrid. A stunt like the above just requires a quick reconfigure to make all emails go via the alternative provider whilst we (with less panic) add another new alternative provider to share the load. It also helps build up a positive reputation before cutting over straight away.
(This wasn't about splitting the emails amongst free tiers to keep it free, we were far away from moving up to a paid tier even with all emails going through one provider.)
A STRANGE GAME.
THE ONLY WINNING MOVE IS
NOT TO PLAY.If the payload is an interpreted script, or something that's compiled (if it can find a compiler, etc) then it may be able to infect different OSes.
That method has got no hope of detecting a modern LCD/OLED/Plasma display.
The majority of enforcement is database driven:-
Royal Mail database of addresses - addresses of current tv licenses = huge list of possible offenders
Now cross check database of possible offenders with databases of: * Sky or Virgin Media subscribers * people who have recently purchased or rented appropriate equipment (televisions, VCRs, PVRs, etc) * etc
Walk in, look at screen(s), walk out.
You wouldn't get to see much of the game at all as most of the time you will be traveling between pubs.
"That's a great question! I think the best way to answer it is..."
(This answer continues for two hours without actually answering the question posed.)
The cost of the raw crude oil is only part (but a significant part) of the pump price.
It's more 'fun' in the UK where fuel duty and other taxes (VAT) form the majority of the pump price:-
